Hello Boys and Girls, Today's lesson is in TWO parts. Part One: It is always a good idea to have a fire extinguisher on hand. One should know where it is and how to use it and test this knowledge occasionally. A good fire extinguisher can prevent a house or a car from burning up. We passed this test today down in the garage. Part Two: Seam sealer is a petroleum product. That means it WILL burn. Quite nicely. Roasting weenies and marsh mellows type flames. Pretty yellow and red ones. I tested this theory today as well. It is TRUE. The result: The fire in my cab was minimal and did no damage. The extinguisher made a hell of a mess but put out the fire RIGHT NOW!. I am changing both shorts and trousers. Thus endeth the lesson.
